The role of air barriers and continuous insulation is multi-faceted and increasingly important in an age of green construction. Air/moisture barriers and continuous insulation are now mainstream building systems that address the demands of more stringent building codes. Air Barriers To meet current building code requirements, air barriers must be properly installed to create a continuous […]

Many of today’s building codes have been updated to better promote airtight construction because that conserves energy and reduces carbon emissions. Architects and builders can choose from a variety of sheathing and air barrier options that seek to address these more demanding 21st century codes. ZIP Systems® wall sheathing and DELTA®-VENT SA, a high-performing water-resistive […]

In today’s green building environment, truly continuous air barriers are king. However, a barrier can become compromised by holes, gaps or other defects. The problems associated with an impaired barrier are amplified when the forces associated with unequal air pressure intercede. Stringent Codes Today’s stringent building codes in both commercial and residential building are enough […]

The success of a design build project depends on many elements in order to get the project completed on time. When something has to be redone, it usually means delays, added costs while playing havoc with a carefully designed construction schedule. Design build contractors continue to use lower cost building wraps that have to frequently […]

The dream of constructing a tunnel 1.4 miles beneath Switzerland’s Gotthard mountain range arose shortly after World War II. Now, that dream has become a reality. On June 29, 2016 the inauguration of the Gotthard Base Tunnel invoked thoughts of Hannibal crossing the Swiss Alps 2,200 years ago. Of course, this route runs under, not over, the […]

It’s important to separate a foundation wall from damp soil so that migrating moisture does not reach the structure’s framing and/or interior. To preempt the costly problems from ground moisture reaching foundations, contractors routinely employ these solutions: Asphalt dampproofing on the exterior surface of foundation walls A layer of polyethylene and crushed stone under the basement […]

Wall designs are one of the most time consuming projects for an architect. As you design buildings that are energy-efficient and compliant with code changes, the wall details become more detail-oriented and evermore critical to the performance of the building. Cosella-Dörken, in collaboration with Roxul, has generated BIM files for wall sections, including air and water-resistive barrier details. […]
